Bruce, does your in-line oiler have a bottom drain valve?
Does the red receptacle fit under that oiler in any convenient way?
No...I just checked Daniel , but I did notice in the link Charlie provided that the fellow seamed to like it sticking out of his smokestack ( I have no idea why you would do that ? ) , I also noticed several plunger syringes ….I also received 3 with this model (not pictured) .
